Clay emerging from a png mill or the like in pieces of any suitable thickness and width is deposited upon the first moving belt 2. From this it is delivered on to the inclined rollcrway 3 down which it slides and accumulates against a second or compression roller 4. A\t`ter passing beneath this roller it emerges in a continuous strip or ribbon. It then passes on to a third ribbed'roller 6 by jwliich it 1s compressed against a series of i `jfourth ribbed rollers 7 the ribs of which are not shown. After passing,between the third and fourth rollers the clay is carried between fifth ribbed rollers 8. Adjacent the fifth rollers is a spindle 9 on which are two star wheels each having three projections 11.

, Between each opposite pair of projections extends a. tine cutting wire 12 which moves a,f.ainst` the ongoing clay and culs it into strips of the desired length equal approximately to the width of the tile. The. sl rip of clay is then picked up by a semi-spiked driven roller 13 which carries it on to a second moving belt or chain lt driven by a sprocket 15.

liy the belt 14 the clay is delivered onto one of a series of lower mold boxesl 16 .formed in a flange 27 of the wheel.

(Figs. 10 to 17). Each mold box has a semicircular trunnion 1T at cach end. These trunnions are adapted to oscillatc within semi-circular beds 18 Jformed in the lower mold box supporting wheels 19 and 2l. In one of the trunnious is a semi-circular recess 22 which accommodates a corresponding projection 23 on the wheelk 19 to retain the end of the mold box in place. At the opposite end of the mold box is a reduced circular neck 24 which passes through a hole 26 Attached to the noch' 24 of each mold box and outside the flange 27 is a ring 28. This ring forms part of a major lever 29lby Iwhich the mold boxes are oscillated. On the outer end of each major lever is a roller 31 which traverses an eccentric pathway hereinafter referred to. Through each mold box are two ejector slots 32 one near each end of the mold face 33. In these slots are steps 34. Formed in the face of each lower mold near one end thereof is a recess 36 which molds a retaining lug 37 (Figs. G and 9) on the underneath face of the' tile. Near each end of each lower mold box is a cross piece 38 forming a roller pathway 39. From each cross piece protrude carrier lugs 41.

In each ejector slot is an ejector 42 having legs 43. AEach ejector is provided with `steps which engage the steps 34 of the slots and limit the inward movement of the ejectors. Pressin against the bottom of the mold box are t e inner ends of coiled springs 44 the outer ends of which press against a plate 4G having projections 45 secured to the legs 43 by screws 47 orlother means (Fig. 21).

A minor or ejecting lever 48 which normally rests against the major lever 29 has on its outer end a roller 49 this lever is secured at'its inner end to a first spindle 51 to which is secured a quadrant 52, this quadrant turns a pinion 53 carried by a second spindle 54 mounted in bearings 55. It also turns with the second spindle two ejecting cams 56 and a core pin 57 which pin. during molding passes through the retainingr lug 37 before referred to and forms a hole 58 therein by which the tilc is bound to the roof.

The upper mold boxes 59 (Fig. 19) are mounted on upper supportingr wheels 61 and G2 (Figs. 1 and 2)in the same manner as the lower inold boxes. From the sides of the upper mold box protrude spue directors (i3. The upper mold boxes have neither the roller paths 39, the carrier lugs 41. the recess 251i, nor the core pin 57, but they are provided with levers and ejectors of theF same eharactcr as those of the lower mold boxes and said ejectors are controlled in the same manner as already described. The minor cjceting levers of the upper mold boxes are normally held against their relative majorlevers by tension springs (il (Fig. l). The faces of the upper and lower mold boxes arc rccessed 'as at 65 to allow' clearance for the projecting parts'of the-opposite mold boxes when the mold faces come together.

After theJ tile has been molded it encounters a side fin cutter which ents ol the tins formed by the material exudin between the molds on each side of the tile. 'l'his side tineutter (Figs. 1, 24 and 25) includes a spindle 6G having thereon two disks G7. In the disks are slotways 68 to permit the ad j ustment of bars G9. To the bars are, attached knives 71 and 72 which are of such contour that. they trim off the fins and leave the sides of the tile smooth. The knives 71 trim off the leading edges of the tiles and the. knives 72 the trailing edges.' ollecting pans (Fig. 22) may be attached te the sides of the mold boxes to receive the surplus material removed by the knives.

The molded tile next encountersend fin cutters (Figs. 1, 26, 27 und 28). One of these cutters is situated at each end of the tile. Protruding from the framework of the machine, are studs 73. To each stud is pivoted a lever 74. This lever has at one end a lug 7G to which is connected one end of a spring 77. The other end of the spring isconnected to the framework of the machine. The lever 7l Supports a spindle. 70 upon which turns a roller 75 which engages the pathway 39 of the lower mold boxes. ,l`o the said level' is attached a plate 7 8 having adjusting slots therein. Through these slots pass screws 79 which hold the plate to the lever. In the said plate turns a pin 81 f which carries a rotary cutting disk 82.

i carrier supplying belt 83.

Adjoining the lower series of molds is a From this protrude carrier lugs Ht eaeh opposite pair of which accommodates the slat 86 of a tile carrier 87 (Figs. 2t) to 3l). llpstanding from the top of each tile carrier is a rib H8 which engages the rear edge 0f the ,forwardly moving tile.

rl`he driving mechanism is as follows1-A first shaftfll has thereon a irst worm 92 which turns a first worm wheel 93 situated upon :n. seeond shaft 94 whieh carries the.

upper mold box supporting wheels and is mounted in bearing-s on the framework 95. The first worm also turns a second worm wheel 96 situated upon a third shaft 97 wli-h carries the lower mold hox supportingr wheels. Means may he provided for adjusting the supportiiucr wheel shafts 94 and 97 to or from eaeh other and also for adjusting the mold hoxes radially on the supporting wheels. Upon the first shaft is a second worm 9H whirh drives a third worm wheel 99 upon a fourth shaft lOl. The fourth shaft. drives first bevel wheels 102 whieh turn a fifth sha ft'lolt. Seeond bevel wheels lill turn a sixth shaft llll' which operates third bevel wheels 107 turning the side, tin cutter spindle GU.

rlhe carrier suppllvingla-lt Sil is driven by :L pulley 117 (Fig. 3) on the fourth yshaft 101. First transfer bells 11S pass over idle pulleys l2() and are driven by frietional eontact with the lower mold boxes. Heeond transfer belts llt) pass over idle. pulleys 125 and with a third transfer belt 121 are driven hy a pulley 12; through ninth bevel wheels 123.

TensioningW rollers 124 may he employed as `shown.

Facing the, lower mold box supporting wheel 2l is a lower stationaryY plate litl (see Fig. -2O) havingr a central hole 12T to pass the shaft. 97. ln this plate is an inner eccentric pathway 128 in whieh run the rollers 31 of the major leveas whieh osrillate the lower mold hoxes. The plate is also provided wilh au outereeeentriey pathway 129 in which vrun the. rollers lt) of the luinor levers which operate the rore pin and ejectors of the lower mold boxes.

Facing the upper mold box supporting wheel (32 is an upper stationary plate lill (see l `ig r. 1S) havin" a central hole |32 to pass the shaft ill. lormed in the plate 131 is an ereentrie pathwa \v 12M in whirh run the rollers of the major levers which oseillate the upper mold boxes. .\l the bottom of this plate is u direi-tor 12H forming' a pathway lflti which is followed b v the rollers of the minor lewi's4 operating the ejectors of the upper mold boxes.

As a lower mold hex approaehes the. feed belt l-t the roller of its respective. major lever engages the straightened portion of the eceentrie pathway 12H which causes the mold hox to heeonie. tilted as shown in Fig. Ql to receive the material from the. belt. rlhe. respective minor lever has up to this point heen separated from the major lever hy the engagement of its roller with the. pathwa)v .-Qfl and the core pin 57 is thus \\ilhdra\\'n. .\s the .rollers approarh the point the converging of the two pathways brings the two levers eloser together and thus moves the, rore pin into the. molding position seen in Fig. 16 so that when the material is eoinpressed in the meid the'pin forms the hole :"9 through the lng' fl7 which is molded within the recess 3G. As the. material is deposited on the face of the lower mold box the, roller of theY major lever ap preaches the, horizontal portioull of the. pathway 198. As the roller enters this porloe 59 the space lictwcenthe carrier lugs 41 on the tion C of its pathway c ausn to the -side'in cutters 71 which remove the i overhanging fin on this side of the tile. As the roller 3l engages the portion D of the eccentric pathway the mold box is tilted in the opposite direction so thatthe trailing edge of the tile is presented to the side fin cutters 72 -whichremove the surplus material' from 4.this side of the tile. Particular attention is called to the fact that the side fin cutters 71 and -72 are rotated slowly, and in proper timed order, so that the above referred to operatiouihay occur. The side fin cutters 71 and 72, receive rotation from a shaft 106, which is driven by a shaft 103.4

The shaft 103 isdrven by a shaft 101, having a' worm wheel 99 secured thereto, which is engaged and driven by a worm 98, carried by the common drive shaft 91. The shaft 91 carries the worm 92, which engages and drives lthe worm Awheel 93. It is thus apparent that the side fin cutters and mold boxes are rotated in a timed order, for effooting the precise coaction, set forth in the specification. The end n cutters are next encountered, the. rollers 75 engaging the pathways 39 while' the cutting disks 82 remove the sur lus material from the tile ends. Meanwhile t e roller of the minor lever has again ,entered the' pathway 129 and the two levers are separated suiciently to withdraw the core pin but not sulilciently to operate the ejectors.

As the roller 31 encounters the straightened portion VE of the pathway-the mold box assumes a vertical position to receive one of the carriers 87 at the point indicated in Fig. 23. y,The s'lh't 86 ofthe' carrier enters mold box sind the carrier moves along with the tile being thus transferred from the supply belt 83 to the first transfer belt 118. As the mold approaches the bottom of the wheel and vflic roller 31 engages the horif/.ontal portion Fo its pathway, the mold assumes a horizontal position face downward. At this point it will be seen that the pathways 128 and 129 diverge from cach other thus separating the minor and ma3or levers suliiciently to engage the cams 56 with thc. bottoni of the ejectors which are llum.f|med outwardly and eject the tile on to the carrier. The carrier and tile are then conveyed along by the second transfor belts 119 on to the third transfer belt 121 which removes the tile to the locality desired. After the tilc has been ejected the mold assumes its normal position and the ejcctors are withdrawn by the springs -il for the molding of the next tile. A positive withdrawal of the ejector-s is assured by engagement of the cams 5() with the top oi the projections 45 as the major and minor levers come. together again.

The contour of the eccentric pathway 13255 is such that the upper mold boxes retain their normal position untiljthc rollers of the major levers approach the horizontal portion G of the pathway at 'which point the mold box is brought into a horizontal position face' downward which position it retains until the tile has been compressed and the roller leaves the portion G of th`e pathway. Immediately after compression has taken place and the upper and lower mold boxes begin to separate the roller of the minor lever engages the director 134 and larly described as adapted to the mo dingzof rooting tiles it is to beV distinctly Vunderstood that it is not limited tosuch use and may be easily adapted to mold metallic or other articles from suitabielnoldable material;
